Use the RAW pin of the PCB for power supply. The Arduino Pro-mini 3.3v regulates the voltage to 3.3v for the HopeRF RFM92/95 module. At the bottom of the PCB are extra connections for powering sensors or other modules.
Only use an Arduino Pro-mini 3.3v version on this PCB!!
The HopeRF RFM92/95 only works on 3.3 volt higher voltage will damage your LoRa module!!
The PCB makes all the necessary connections from the Arduino to the HopeRF RFM92/95 module.
MISO, MOSI and SCK are connected to the standard arduino pins.
The only thing you need to change in your sketch are the DIO and the NSS pins
Short manual how to get this board working TTN V2— New Tutorial TTN V3
This board is tested with the following libraries:
Change the pin-mapping in your sketch to mach with the pin-out table below. (DIO0, DIO1, DIO2 and NSS pin)
If you use the LoRa-lmic library you must provide your – network session key, application session key and device address.
